Animals having a tendency to align their velocities to an average of those of their neighbors may flock as illustrated by the Vicsek model and its variants. If, in addition, they feel a systematic contrarian trend, the result may be a time periodic adjustment of the flock or period doubling in time. These exotic phases are predicted from kinetic theory and numerically found in a modified two-dimensional Vicsek model of self-propelled particles. Numerical simulations demonstrate striking effects… Expand
Spatiotemporal dynamics of a self-propelled system with opposing alignment and repulsive forces.
The extent of synchronization of the particles' motion is analyzed through a Hilbert transform-based mean frequency approach, leading to the detection of a weak chimera state in the case of the spatial structures. Expand
Phase transitions in non-reciprocal active systems
Crowds, flocks of sheep, robotic swarms or firing neurons are examples of active systems composed of energy harvesting units that move or interact according to the state of their neighbours. TheExpand
Active Ornstein-Uhlenbeck particles.
A theorem on the time reversed form of the AOUP Langevin-Ito equations is proved that they have an equilibrium probability density invariant under time reversal if and only if their smooth interaction potential has zero third derivatives. Expand
Phase transitions in non-reciprocal matter.
Out of equilibrium, the lack of reciprocity is the rule rather than the exception. Non-reciprocal interactions occur, for instance, in networks of neurons, directional growth of interfaces, andExpand
Beating the natural time scale for relaxation with optimal control
We consider the relaxation of a driven granular gas, as the prototypical example of an intrinsically non-equilibrium system, between two non-equilibrium steady states. For time-independent driving,Expand
Linear response in the uniformly heated granular gas.
We analyze the linear response properties of the uniformly heated granular gas. The intensity of the stochastic driving fixes the value of the granular temperature in the nonequilibrium steady stateExpand
Optimizing the relaxation route with optimal control
It is shown that analogous bang-bang protocols, with a number of bangs equal to the number of relevant physical variables, give the minimum connecting time under quite general conditions. Expand
Analysis of aligning active local searchers orbiting around their common home position.
The effects of pairwise aligning interactions in an ensemble of central place foragers or of searchers that are connected to a common home and expressions for the critical interaction strength, the mean radial and orbital velocities of the searchers and their velocity variances are discussed.

Non-reciprocal phase transitions.
This work lays the foundation for a general theory of critical phenomena in systems whose dynamics is not governed by an optimization principle, and captures non-reciprocal generalizations of three archetypal classes of self-organization out of equilibrium: synchronization, flocking and pattern formation.

Tricritical points in a Vicsek model of self-propelled particles with bounded confidence.
It is demonstrated that the reduction of the restriction angle leads to a critical noise amplitude decreasing monotonically with that angle, turning into a power law with exponent 3/2 for small angles, and the critical noise is always smaller than the threshold noise for the transition from disorder to polar order.

Hydrodynamics and phases of flocks
Abstract We review the past decade’s theoretical and experimental studies of flocking: the collective, coherent motion of large numbers of self-propelled “particles” (usually, but not always, livingExpand
Kinetic theory for systems of self-propelled particles with metric-free interactions.
This confirms previous direct simulations that, for Vicsek-like models with metric-free interactions, there is no formation of density bands and that the flocking transition is continuous. Expand
From phase to microphase separation in flocking models: the essential role of nonequilibrium fluctuations.
It is shown that the flocking transition in the Vicsek model is best understood as a liquid-gas transition, rather than an order-disorder one, which highlights an unexpected role of fluctuations in the selection of flock shapes. Expand
Collective motion of self-propelled particles interacting without cohesion.
The onset of collective motion in Vicsek-style self-propelled particle models in two and three space dimensions is studied in detail and shown to be discontinuous (first-order-like), and the properties of the ordered, collectively moving phase are investigated. Expand
Collective Behavior of Chiral Active Matter: Pattern Formation and Enhanced Flocking.
The results defy the viewpoint that monofrequent rotations form a vapid extension of the Vicsek model and establish a generic route to pattern formation in chiral active matter with possible applications for understanding and designing rotating microflocks. Expand
Hydrodynamic capture of microswimmers into sphere-bound orbits.
This study reveals the crucial aspects of activity–driven interactions of self-propelled particles with passive objects, and brings into question the use of colloidal tracers as probes of active matter. Expand

A ring-kinetic theory is derived for Vicsek-style models of self-propelled agents from the exact N-particle evolution equation in phase space and it can handle precollisional correlations and cluster formation, which are both important to understand the phase transition to collective motion. Expand
Collective Motion
It is demonstrated both numerically and analytically that even in certain one dimensional self-propelled particle systems an ordered phase exists for finite noise levels. Expand
Emergent spatial structures in flocking models: a dynamical system insight.
It is shown that hydrodynamic theories of polar active matter generically possess inhomogeneous traveling solutions that correspond to those hitherto observed in experiments and numerical simulation: periodic density waves, and solitonic bands, or polar-liquid droplets both cruising in isotropic phases.
